摘要: 提出一种用压电材料(PZT)和人工神经网络控制理论相结合的方法,对悬索桥梁结构健康状态进行在线诊断,以便及时修复。该方法利用PZT受力变形时电压电场变化的机理采集信息,结合改进了的BP神经网络控制方法,对悬索桥梁的应力、应变进行在线分析和智能诊断。并通过实验研究获得大量的实验数据,对BP网络参数进行优化,证明了该方法的可行性和先进性。
关键词: 压电陶瓷BP人工神经网络悬索桥梁智能检测    
Abstract: A new method using piezoelectric material (PZT) and artificial neural network control was put forward to repair in time by online monitoring the health state of cable suspension bridge. This method conducted online analysis and intelligent diagnosis on stress and stain of the mentioned bridge, which adopted the principle that when PZT had distortion, the voltage and intensity of electric field would change, to collect information and the improved ANN control. A great deal of data was obtained from experiments, and then the parameters of BP ANN were optimized, which demonstrated the feasibility and advancement of this method.
Key words: piezoelectric material    BP neural network    cable suspension bridge    intelligently monitor
